How to fix Terraria does not start / immediately exits on Linux
If your Terraria exits immediately and the Terrria window never appears, try
cd ~/.local/share/Steam/steamapps/common/Terraria
./Terraria.bin.x86_64 > terraria.log
As it turns out, Terraria only starts properly on my machine if you redirect stdout to a file (or pipe it into another program), hence > terraria.log
is neccessary to get it running.
